Hello, I've got a 2year old Buff Orpington who is acting completely normal but her droppings are bright green. There are 7 girls total and this is the only one with the green droppings. Her bum was quite dirty and tinted green so I gave her a bath. She's drying out in the bathroom right now eating and drinking. The droppings did smell quite rotten. I haven't fed them anything recently that would change their dropping colors. Any ideas?
